Introduction Auronik offers leading-edge communication solutions according to DIN70121 and ISO15118. These solutions currently comprise the 3rd generation PLC and PWM communication hardware EVAcharge SE and the corresponding communication software ECommStack both for DC and AC charging. The board contains the PLC communication via CP with PWM generation and HomePlug Green PHY integration and can act as EVSE as well as EV. Along with these communication components comes the fully standard compliant electric vehicle communication simulator DC.chargeSTRESSOR with the capability to execute conformance tests according to DIN70121 against charging spots. This document contains the technical specification of the PLC and PWM communication board EVAcharge SE. Attention: Any changes or modifications to this appliance which have not been explicitly approved of by the respective regulatory authority, may lead to a prohibition of usage of this appliance. Protection of the electrostatic-sensitive device (ESD) OBSERVE PRECAUTIONS FOR HANDLING ELECTROSTATIC DISCHARGE SENSITIVE DEVICES The EVAcharge SE board is an electrostatic-sensitive device (ESD) which can be damaged by common static charges which build up on people, tools, and other non-conductors or semiconductors. For ESD protection Auronik recommends the following practice: establish an ESD protection area, wear antistatic garments and use an antistatic wrist strap, use a grounding mat or other grounding tools to prevent damages, never open the ESD-safe bag of the EVAcharge SE board outside of your protection area.

Application of EVAcharge SE The application purpose of the EVAcharge SE board is to provide a hardware solution for charging spots with regards to DIN70121 and ISO15118 compliant signalling utilising GreenPhy power line communication (PLC) over pulse width modulation (PWM) technology (ISO layer 1 and 2). The boards are being integrated into charging spots and physically connected to the power electronics. To communicate with EVs it supports CP (control pilot) and PP (proximity pilot) signalling. Customer specific software interface adaptations take care for proper data exchange between power electronics and the EVAcharge SE.

LEDs The physical location of the LEDs are depicted in subsequent figure. Fig. 4: LEDs on EVAcharge SE board LED0 (red) The LED is connected to the i.mx28 pin K4 / AUART1_TX. Default behavior is the Linux system clock of the i.mx28. LED1 (yellow) The LED is connected to the i.mx28 pin L4 / AUART1_RX. LED2 (yellow) The LED is connected to the i.mx28 pin T3 / LCD_D16. LED3 (green) The LED is connected to the i.mx28 pin P2 / LCD_D08. EVACHARGE SE - DATASHEET - FEBRUAR 2016 6
LED4 (yellow) The USS command indicator of the co-processor. Each time an USS command is received by the host and processed the LED flashes for a short time. If the co processor stays in bootloader (immediately after reset for a few seconds) this LED is always on. LED5 (green) The co-processor life sign. The LED blinks in a second interval showing the co-processor is working and alive. If the co-processor stays in boot loader (immediately after reset for a few seconds) this LED is always off. Connectors The following picture of EVAcharge SE gives an overview of all relevant connectors. Fig. 5: EVAcharge SE board with marked connectors EVACHARGE SE - DATASHEET - FEBRUAR 2016 7
Debug UART (JP1) Fig. 6: Debug UART in detail JP1 Pin Name i.mx28 Pin 1 GND - 2 not connected - 3 not connected - 4 RX of i.mx28 K7 / PWM0 5 TX of i.mx28 L7 / PWM1 6 not connected - This pin-out is compatible with a variety of USB/RS232 adapters. Preferably you should use the FTDI cable TTL-232R-3V3 or similar. ATTENTION: Do not use generic RS232 adapters, as they usually have +-12 V voltages for their logic signals. The pins here are only 3.3 V tolerant. You may damage the debug UART with incompatible adapters. Use the following settings to connect to the debug UART: Setting Value Baud Rate 115200 Data bits 8 Stop bits 1 Parity None Flow control None EVACHARGE SE - DATASHEET - FEBRUAR 2016 8
Voltage Input (X4) Fig. 7: Voltage input connector X4 Pin Name 1 +VIN 2 GND CAN Connector (X5) Fig. 8: CAN connector This connector can be used to connect to the i.mx287 using CAN. To set the board to CAN mode set the jumpers JP8 as shown in figure 9. Pinout of X5 X5 pin Function in CAN Mode 1 not connected 2 CAN_L 3 GND 4 not connected 5 not connected 6 not connected 7 CAN_H 8 not connected 9 not connected EVACHARGE SE - DATASHEET - FEBRUAR 2016 9
CAN Selection (JP8) Figure 9. JP8 in CAN MODE CAN Termination (JP4 and JP5) The CAN termination resistor of 120 Ω can be enabled by setting both jumpers JP4 and JP5 (standard using). Removing both jumpers disables the termination resistor. Fig. 10: CAN termination jumpers JP4 and JP5 EVACHARGE SE - DATASHEET - FEBRUAR 2016 10

Boot Selector Jumpers for i.mx287 (JP6 and JP7) Fig. 16: Jumper JP6 and JP7 for booting from emmc The both jumper settings select the boot source for the i.mx287. Attention: From board revision V0R4 and higher it is no longer necessary to set any jumper for booting from e.mmc (standard use). Means: No Jumper > booting from e.mmc EVACHARGE SE - DATASHEET - FEBRUAR 2016 13
The other possibility is to set the boot source from USB. This is prepared for engineering purposes only. Normally the costumers will not use it. Fig. 17: Jumper JP6 and JP7 for booting from USB (J3) EVACHARGE SE - DATASHEET - FEBRUAR 2016 14
Mounting holes EVAcharge SE supports nine mounting holes, as shown in figure 18. Fig. 18: Mounting Holes of EVAcharge SE H1... H4 - main PCB mounting holes H5... H9 - daughter board mounting holes Attention: Please only use insulating mounting material on all mounting holes, which are used. Do not change the mechanical properties of the board (no bending, sawing, drilling, filing ). This would have an essential influence on its function. Your warranty will be lost.
